PATRICK J'. HEALEY, OF JERSEY CITY, NEW JERSEY.

GRAB BUCKET.

Application led March 4, 1922. Serial No. 540,949.

To all whom 'it may concern.' y

Be it known that I, PATRICK J. HEALEY, a citizen of the United States, and resident of the city of Jersey City, county of Hud-i son, State of New Jersey, have invented certain new and useful improvements in Grab Buckets, of which the following is the specification.

The device the subject of this invention is a grab bucket, particularly designed vfor use in cleaning catch basins inv street drains or sewers and has many elements of construction differing from that of the ordinary grab bucket. 1

A particular object of the invention is to provide a bucket made in cylindrical form and having jaws that open outward beyond the outer periphery of the cylinder, so that an area greater than that included within the outline of the cylinder may be reached.

Another object of the invention is to provide means for urging the bucket through the mud and sludge in the basin, such means consisting of ya movable weight arranged within the bucket.

Another object of the invention is to provide means whereby the jaws of the bucket are closed by the lifting cable, assuring that the jaws are fully closed before the bucket is moved.

Another object of the invention is to provide a scraper or means for gathering the material local and adjacent to the jaws of the bucket, so that the jaws may readily gather up the material into the bucket.

Other objects of the invention and the details of construction will be fully set forth as the specification progresses and the accompanying drawing should be referred to for a complete understanding of the specilication which follows:

In the drawing:

Fig. 1, is a side elevation of the bucket with the jaws closed.

Fig. 2, is a central, sectional `view of the device as shown in Fig. 1.

Fig. 3, is a central, vertical section of the device with the jaws open,

Figs. 4 and 5, are fractional, partial, sectional views of modifications.

Fig. 6, is a side elevation, of one jaw, showing the scraper in position.

Similar reference numerals indicate like parts in all the figures where they appear.

At 10, I show the body of the bucket which in the preferred construction will consist of a cylinder, having a bail 11, secured at and projecting from the upper edge of the cylinder 10 and in the bail, I provide aneye 12 for a purpose to appear later.

The bottom of the cylinder 10 is closed by means of jaws 13 and 14 which together complete a cone shaped projection from the bottom of the cylinder, each jaw isl secured to the cylinder by a hinge as shown atv15 and 16 and as shown in Fig. 3 the jaws may open outward so thatthe eXtreme edges of the jaws will project beyond the line of the cylinder. The'jaws may be provided with perforations as shown at 17, by means of which water may pass from the cylinder.

The jaws 13 and 14 are each provided with lugs as shown at 18 and 19 and in each lug, l arrange a link 20 or 21, one of which is connected to each of the vertical bars 22 and 23. These bars terminate in and are connected to a washer or plate 24 secured adjacent the movable weight 25 by means of the eye-bolt 26 and rods 27 and 28 secured in the weight25 pass through lugs as shown at 29,30, 31 and 32 to impinge upon the brackets 33 and 34 for a purpose that will be referred to in the descriptionl of the operation.

l provide a rin 35 within the cylinder 10 and upon whic the weight 25 may engage.

In the operation of my device, the bail 11 is engaged and retained, while the lifting cable 36 is slackened allowing the weight 25 to move downward and through the bars 22 and 23 and links 2O and 21, opening the jaws 13 and 14 to their full extent if desired.

The bucket is then lowered into the catch basin and may be guided to any part thereof. The weight of the bucket and especially the weight of the member 25 urges the jaws 13 and 14 through the sludge and refuse in the catch basin, the jaws are then closed by tension applied to the rope 36 and the bucket is withdrawn from the catch basin to deposit its contents wherever desired.

It will be noted that the jaws are retained open by means of the rods 27 and 28 resting upon the brackets 33 and 34 and cannot be closed until the weight 25 is lifted.

As the free ends of the jaws 13-14 are pointed I may provide a scraper member as shown at 37 in Fig. 6 which member may be of any desired width and which may be secured to the free end of the jaws 13 and 14. The scraper consisting of two elongated members arranged parallel to each other and extending outward to anj7 desired degree, the middength of the scraper may be shaped as shown at 38 to conform to the shape or outline o the jaw.

I have found it desirable to provide means for imparting a hammer blow from the weight through the rods 27 and 28 to the jaws of the bucket. If accomplish this in either ofthe methods shown in Figs. 4 or 5. In Fig. 4, I provide an elongated bolt 39 to which the plate or disk 24 is secured, the rods 22 and 23 terminating in this plate 24 and from this construction it will be observed that the weight 25 may be moved upward and downward to certain extents independently of the jaws 13 and 14, but when movedlupward to its full extent, the head-40 ofthe bolt 39 will also be moved closing the jaws.

' that shown in Fig. 4.

I may provide independent cables for'the weight 25 and bail 11. The additionallcable serving to retain the bail when the jaw-sY are'to be opened or for changingthe position ofthe cable without changing the position of the jaws, but the addition of one or more cableson a grab bucket is not'V considered invention due to the presentstatelof'the art. The sizeandy general shape ofthe bucket may be changed at will and other modifications may be madewithin the scope of the appended claims without departing 40 from the principle or sacrificing the advantages of the invention.

Having'carefulljf and fully described my invention what I claim and desire to obtain by Letters Patent'o'fthev United Sta-tes v45 is as follows l. Ar grab bucket having jaws, a weigh-t within said-bucket for urging said bucketV down-ward guides for said weighty and* brackets uponsaid jaws, upon which said* parallel rods secured to said l'weighted mein-Y 55 ber andlinks extending-.trom said 'parallel' rodsto said jaws.

3. A grab bucket having javvs-"'and`v a1 weighted member 'for'operatingI said jaws,

parallel rods secured tov said weighted fmem 00 ber and l links extending from saidA parallel rods to said jaws, brackets upon-saidfjaws and additional parallel rods securedv tosaid; weighted member and i adapted' to' engage uponsaid' bracketsA Afor retaining said :jaws 65 open.
